As materials having a cushioning property such as interior parts ofautomobiles, shoe soles, cushioning materials and the like, laminatesmanufactured by laminating a skin layer and substrate layer on a foamedlayer of polyurethane manifesting a cushioning property are used, andconventionally, a vinyl chloride resin and the like are used as the skinlayer and the substrate layer. However, from the standpoint of recentenvironmental problems, materials substituting for a vinyl chlorideresin are desired, and as these materials, studies are being developedusing an olefin-based or styrene-based thermoplastic elastomer. However,since adhesion between an olefin-based or styrene-based thermoplasticelastomer and a polyurethane is not sufficient, it is necessary to usean adhesive and primer containing an organic solvent for obtaining astrong laminate as disclosed, for example, in JP06-246858A. However, thetechnology using this adhesive has a problem of deterioration in workingenvironments due to an organic solvent contained in the adhesive, inaddition to process complexity owing to an application process of anadhesive.

The contents of the repeating units (a) and (b) in the copolymer (A) arepreferably 5 to 40% by weight and 60 to 95% by weight, respectively.When the content of the repeating unit(a) is less than 5% by weight, anadhesiveness to a polyurethane may become insufficient. On the otherhand, When the content of the repeating unit (a) is more than 40% byweight, the storage stability may deteriorate. Herein, the sum of thecontents of the repeating units (a) and (b) is 100% by weight.
